Is there a substitute for poke face option in Blender 2.65?
If @batFINGER's suggestion doesn't work for you for some reason, then, with Pivot set to 'Individual Origins', in Face mode you can I inset all your faces a little way (or by no distance) :

.. With 'Individual' checked. (This illustration has to be in a later version, but your adjustment should be available in the T toolbar region.)
Then S0 you should be able to scale all faces to 0, followed by the old AltM &gt; B .. or W menu .. 'Remove Doubles'.
